Abstract
Abstract In a tire mounting and demounting apparatus, a carriage is slidably mounted to an enclosure adapted for reception of an upright tire assembly. A plurality of individually actuatable rams are mounted to the enclosure and carriage, particular rams being adapted for positioning of the carriage within the enclosure and other rams being adapted for selective engagement and disengagement of the tire assembly. In the demounting of a wheel from a tire, the positioning rams are actuated individually until the engagement rams and the wheel is in spaced relation. Thereafter, the engagement rams are actuated selectively for engagement and disengagement with the wheel, in consequence the adhesive bond between the wheel and tire is broken and removal of the wheel from the tire is facilitated.
